Why would an old project not recognize my phone?

[Joseph Nardone]

Hi:

I am trying to open a project that is over a year old to get some code to help someone on the forum out. I want to test the code on my iPhone 4 to make sure that it still works but XCode will not show my phone to select to run the app on.

It will show my iPad if I plug it in and other projects are showing my phone fine. The code runs on the simulators (iphone and iPad) but I need a feature of the device.

The app was written when the current iOS was 3.0 and my old phone was a 3G. My phone now is an iPhone 4.

Where should I look for a problem.

Does your phone get mounted as a external drive (does it appear on the Desktop as an icon)? I'm not sure if that will prevent it from being used by Xcode or not, but that's the only thing coming to mind.

See if it shows up in Organizer (cmd-shift-2 in xcode). Click devices on top, then your phone on the left. If there is a button "Use for development", you need to do that before it will show up. It takes a minute or two (loads symbols or something like that).

If the button doesn't show up, you might need to do a restore on your device first. I've had odd problems with devices not showing up and was able to fix it that way.

EDIT: Just noticed this:

This is pretty strange. Maybe check the "iOS Deployment Target" under your project settings to make sure it didn't get set to an iOS version higher than what's on your phone?
